A motor spins up the flywheel with a constant torque of 50 n⋅m. how long does it take the flywheel to reach top speed?

dimulka [17.4K]

A motor spins upward the flywheel with a persistent torque of 50N⋅m.

What time does it take the flywheel to get to the top speed?
From the equation:
Tj = J*dω/dt

you can get the two equations:
Δt1= J1*Δω/Tj = 240*125.66/50 = 603.17 sec
Δt2= J2*Δω/Tj = 120*125.66/50 = 301.58 sec

The distance from earth to a NASA satellite traveling through the solar system is 6.0 × 109m. A command is sent to the satellite

alexandr1967 [171]

Answer:

the signal it takes 40 s to get the answer

Explanation:

As the satellite is in space the speed of radiation (waves9 is the speed of light in a vacuum, which is constant 3. 108 m / s, so we can use the uniform motion ratios to find the time.

v = d / t

t = d / v

t = 6.0 109 / 3. 108

t = 2 101 s

t = 20 s

This is the time it takes to get the signal from the earth to the satellite and it takes the same time to return, so since they send the signal it takes 40 s to get the answer
